Any Literature on Bosch HFM-SFI engine management systems?
I've been long trying to source and in depth literature on this system. Does anyone know of any place I can download, view, even purchase a good book on this system? I'm looking to explore the methods in which the variable valve timing, ignition timing, ect all operate. Even possibly something that sheds some light on the mapping of the system.

The Bentley book has a very in depth electrical digram as well as a multimeter troubleshooting guide for the system. I have the book if you ever want to borrow it.
This book doesn't go into the details you want though. I don't think any literature will. But all the things you mention can be easily source by OBD-2 mapping, which I also have the equipment for.
i can have the book in the office, you can stop by, grab it, make copies and just drop it off there whenever you are done.
